Is this an okay way to mount gantry to linear bearings?http://www.mycncuk.com/threads/11711-Is-this-an-okay-way-to-mount-gantry-to-linear-bearings?goto=newpost

I want to mount short gantry sides to 20mm hiwins.
I want the gantry mounted on top of carriages, with weight centered instead of mounting them side on.

I have came up with this little aluminium mount/adapter that will attach to the gantry sides with 3x M8 bolts.

I'd love some comments on the concept... is there a better/easier way?
Does it look stable?

I dont know what im doing LOL, please guide me : -)

Sat, 17 Feb 2018 08:24:36 GMTI've stumbled randomly across an eBay advert (eBay, UK, item 112812638856) which advertises 20mm square rail at 2 of 400/700/1000mm (6 pieces in total), 12 carriages for the rail, and 1605 C7 ball screws and balls at the same lengths of 400/700/1000mmm (and blocks and couplers).

All for around £370 including delivery from a German warehouse (so no import duty).

Am I being naive here, or is that a pretty good price?

Okay, it constrains my design for a machine a little (from 1200mm to 1000mm) and would have to source a second screw/nut for the 1000mmm) but it looks an attractive price to get the major bits for a small hobbyist router intended for cutting aluminium. Or, are these prices (including the EU location) pretty much achievable elsewhere? (I know I struggle to get remotely close with UK suppliers).

I'd like to put up for sale my Denford Triac, I bought this a year ago but since buying another machine I no longer have time to spend on it.
It has been converted to servo somewhere along the line but not by me.
It does run but needs a little more work.

Its had new spindle bearings fitted professionally by a local cnc machine repair shop. matched pair of 7208 B P5 angular contact bearings which I can provide receipts for as well as the work carried out.
New X axis ball screw and nut, I wasn't happy with the one I fitted to begin with so have another Inwin screw and nut machined but yet to be fitted.
Rebuilt limits and home switch bracket for the x axis

Servos are electrocraft E240 table below shows the specs for them.

*wiring to the X axis in the pic below is temporary just for testing the ball screw.
I'll put up the details of the control electronics below

Its tatty looking but fully serviceable , has a working oiler and all axis drives are working as well as spindle control in mach 3. It really just needs someone with more time than I have right now and It would easily compete with the likes of a Syil X5 but with servos I think probably more accurate.

Im selling this as a project, rather than a ready to work machine. Id have loved to fully restore It but have now run out of time and space so it needs to move on, price covers what ive spent on it.

I can provide more pictures on request, also It comes with paperwork for most of the components.
Comes with an R8 ER32 collet holder.
I have a small Dell Pc, monitor Keyboard and mouse that I will include in the sale to get you up and running.

£1500 ono collected from Winchester. I have a hydraulic trolley here that could get it to the back of a van if needed.

I am trying to understand the DDCSV controller's command language. I am posting on MadModder as this is where a lot of the early work was done but I know a number of people here are using this hardware but maybe not on MM.

It just would save me posting everything twice.

Cheers

Will

I have a spindle that needs bearings, its a QC30 and i want to fit in my BR2J head.

Does anyone know of suitable bering codes - i have read stories that quote super-special-££££ items and then this that fitted off-the shelf items and all are happy, seems a good angular contact pair is needed but what code do i search for??

Any help appreciated.

Could anyone assist me in adding these cheap engraving bits into the tool library on fusion 360?

I have taken the front panel off and the LCD panel has part number: YXD-19264H15B

I don't see mto be getting anywhere with Syil direct, so thought I would try here.

Any thoughts?

I have bought a kit with a Nema24 motor and driver M542T and a MPG wheel and 36v power supply in an attempt to learn how I can use steppermotors for different things. I am not an complete newbie to electronics but many components I do not know how works, so not to burn of my new gismos I have some questions.
I do not want to use them in CNC machines but just to move things in a precise distance, like the Z axis on my milling machine (fitted with DRO) with the least amount of components and without the use of CNC software.
And here is my question. In the manual for the driver M542T it says that it can accept Line Driver Signals on Pul and Dir ports and I found on the internet a Tosoku MPG with 6 connectors like the one I have, so am I supposed to connect my MPG to the driver (I hope you can see the the writing on the MPG) like this, on MPG A to driver PUL+, MPG A (with line over) to driver PUL-, on MPG B to driver DIR+, and on MPG B (with a line over) to driver DIR-.
I this is correct and working, then my next question is, is it possible to multiply the signals from my MPG like remote MPG pendants for CNC machines with a switch for x1, x100 and x1000 so that x1 is my MPG without multiplying and a switch that switches my MPG signal over to 2 gizmos for x100 and x1000 if you know what I mean.
Kind regards

Mon, 12 Feb 2018 17:52:47 GMTNeed a little help on a more reliable cutting process, the only issues I'm having is profiling and was going just fine for about 6 off of the pictured parts.

I'm Dave and live in Lincoln. I'm new to CNC (well I did write a simple programme at college many years ago...) and want to get into it as I tune two stroke bikes. I would like a CNC machine to cut different combustion chamber designs for testing along with other cool stuff you could do with these machines. Clearly I need to learn Fusion 360 too!

Currently I can weld chambers up and machine them with a form tool in the lathe but I see having a CNC machine would make life much easier and accurate.

Testing is then carried out on my Fuchs motorcycle dyno.

I just missed out on the Mikini 1610 that was on Ebay... if I'd been a few days earlier I'd have got it but that's how it goes sometimes... I'm was after a Denford Triac and looks capable of machining combustion chambers but I'll just have to see what comes up.

I like building 2 stroke expansion chambers too and after years of doing lobster back headers I have just started experimenting with hydroforming.

So there you go - that's about me. Hopefully I can find a CNC machine and get it in the garage soon to help make even more power on my Suzuki X7.

Cheers

Dave

I looking for some guidance on a replacement 4 axis controller and driver boards.
I have a DIY cnc set from Roy cnc (I think) which water has gotten into, the only thing left is the enclosure.
I have been looking about without much success, there is a few on ebay but I don't know what I'm buying.
Any suggestions would be much appreciated.

Mon, 12 Feb 2018 12:13:12 GMTHi, I have an Bridgeport EZ Path S - apart from a burn't out motherboard that I replaced 4 years ago it has been working great. However yesterday it suddenly stopped and gave the error Axis Drive Fault.

Several clicks are heard from the back. Under investigation in the back the A1 box (Spindle drive ) has LEDs on it that show 0.0 and then the K1 (contactor enable spindle drive auxiliar) clicks on and off - then Uu is displayed on the A1 box (large U next to a small u "Uu"), then the A1 box goes off.

When the machine starts up it says Machine not homed yet - press 3 and start. As soon as I do this then the above happens.

At first i though it was the X -axis as that is the first to home - however now I am assuming that something has happened to the spindle drive??? But what? Are there any tests I can do?
